Immunogen TFE3-L Protein
Clone G138-312
Isotype IgG1
Characteristics 1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Please refer to us for technical protocols.
3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
Purification Purified from tissue culture supernatant or ascites by affinity chromatography.
Alternative Name TFE3
Background TFE3 is a ubiquitously expressed 50 kDa transcription factor containing both basic helix-loop-helix (bHLH) and leucine zipper (ZIP) motifs. It was initially identified as a protein which bound to the µE3 site in the immunoglobulin heavy chain enhancer. In addition, it binds to the MLTF/USF site in the adenovirus major late promoter. Upon binding as a dimer, it induces a minor groove-oriented bend in the DNA, similar to other HLH proteins such as TFEB, USF, myc, and max. Binding results in transcriptional activation and is mediated through the basic region located just N-terminal to the HLH domain. Clone G138-312 recognizes TFE3. The antibody was raised against a bacterially expressed TFE3-L protein consisting of 327 amino acids encoded by nucleotides 361-2469 of the cloned cDNA.
Molecular Weight 50 kDa
Research Area Chromatin and Nuclear Signaling, Transcription Factors, Adaptive Immunity
Application Notes Applications include western blot analysis (0.25-1.0 µg/ml). WI-38 cells are suggested as a positive control. Other applications include gel shift (supershifts) and immunoprecipitation, which are not routinely tested. The antibody has been used to detect in vitro translated TFE3-L and TFE3-L, expressed as a recombinant protein in bacteria. In gel shift assays, using µE3 as a probe, this antibody supershifts the complex.

anti-Transcription Factor E3 (TFE3) antibody Western blot analysis of TFE3. Lysate from WI-38 cells was probed with anti- TFE3 (clone G138-312) at concentrations of 1.0 (lane 1), 0.5 (lane 2), and 0.25 myg/ml (lane 3). TFE3 is identified as a band of 50 kDa.
